I'm sure it's been asked or talked about but is it good to run 93 in a stock SHO? I've heard it's good? A tune would help definitely but since i daily drive mine I feel a difference in performance like it has more "power" per se. I'd think the PCM would adjust for the higher octane to advance timing? I'm sure I've asked my own question but was looking for opinions from yall! Thank you! 2015 SHO bone stock!

It will help on that reason you stated. Also the top tier gas and 93 come with detergents. Until you tune of go with a Gearhead auto octane tune will you feel a boost between grades. All modern cars can make small adjustments to timing based on octane

I only run pump 93 in my '14 SHO. With a K&N panel filter, it put down 318hp, 345tq to the wheels. I need to get the GH AO tune and possibly an E20-E30 tune to make more power.

Yep, 93 in everything that I own that requires it or has it as an option. Otherwise, regular and an additive cleaner every oil change.
